Schematic Representation Of Spermatogenesis And Oogenesis

Spermatogenesis Vs Oogenesis

In spermatogenesis

A schematic representation of spermatogenesis is given below. Correctly identify A,B,C and D by selecting the option:

What is spermatogenesis? Give schematic representation of spermatogenesis.

(a)Give a schematic representation of spermatogenesis in humans . (b) At which stage of life does gametogenesis begin in human male and female respectively ? (c )Name the organs where gametogensis gets completed in male and female respectively.

With reference to the above schematic representation of (a) SQPermatogenesis and (b) Oogenesis answer the following questions: (a) About 300 million SQPermatozoa may be present in a human male ejaculation at one time. Calculate how many SQPermatocytes will be involved to produce 300 SQPermatozoa. (b) How many chromatids are found during Oogenesis in (i) Primary oocyte and (ii) First polar body in a human female?

Define gametogenesis and explain the diagrammatic representation of spermatogenesis.

Differentiable between spermatogenesis and oogenesis.

(a) Describe the events of spermatogenesis with the help of a schematic representation. (b) Write two differences between spermatogenesis and oogenesis.
